## cali2 Group Title factorise y^3-10y+3 one year ago one year ago

1. Yacoub1993

$y ^{3}-10y+3=0$ $y ^{3}-10y=-3$ $-9y ^{3}=-3$ $y ^{3}=\frac{ -3 }{ -9 }$ $y ^{3}=\frac{ 1 }{ 3 }$

@Yacoub1993 Check the third step.

y^3 and 10y not like terms???

4. Yacoub1993

6. Yacoub1993

y you are putting it equal to zero??? @Yacoub1993

its finished like that

11. Yacoub1993

so that i factorize it

12. rizwan_uet

no no basically what you are trying to find a value of y such that if you put it in this equation will result in zero not to factorize it

13. Yacoub1993

ahha understood @rizwan_uet u should be my tutor for real :)
